Just think of courting women as a skill that you need to improve. That's not changing who you are as a person, at all.
If I start to learn how to play guitar, am I completely changing who I am?
You're just learning to be better at a skill or aspect at life you'd like to improve.
Think of it this way, as a PC. You think we're asking you to rip out the motherboard and replace all the internal hardware. When really you just need some new software. Same machine, but more capabilities.
